Underground direct plug of conductive cylinder glue injection type

Abstract

The invention provides an underground direct plug of a conductive cylinder glue injection type. The plug comprises a direct plug housing, a conductive cylinder which is arranged in the front part of the direct plug housing and is provided with an insulating layer; an insulating contact pin with an insulating sleeve which is arranged in the middle of the direct plug housing. A direct plug tail housing which is adaptive to the direct plug housing is arranged at the tail part of the direct plug housing; a cable stripping head is arranged in the direct plug tail housing; the cable stripping head is connected with the insulating contact pin; a lip sealing ring is arranged at the front end of the direct plug housing; a direct plug connecting screw cap and a direct plug positioning sleeve are sequentially arranged outside the direct plug housing; a direct plug tail connecting ring is arranged at the connecting part of the direct plug housing and the direct plug tail housing; a direct plug sealing stop block is arranged at the position of the insulating contact pin in the direct plug housing. An insulating contact pin pressing plate is arranged at one side of the direct plug sealing stop block, and a pressing gasket is arranged between the insulating contact pin pressing plate and the direct plug sealing stop block; a glue injection layer is arranged between the direct plug tail housing and the cable stripping head, and a tail pressing ring is arranged between the glue injection layer and the tail housing.

Description

technical field [0001] The invention relates to a straight plug used in conjunction with the main body of a cable passer, in particular to a conductive cylinder glue injection type underground straight plug, which belongs to the technical field of electric equipment. Background technique [0002] With the development of my country's oil exploration and development, the development of oil wells is becoming more and more intensive, and the integrated oil production technology of electric submersible pumps used in conjunction with it has also been developed rapidly. The upper penetrating oil pipe hanger and the upper flange, and connects the downhole electric submersible pump and the uphole power supply device, it has changed the traditional cable crossing method, and has the characteristics of good safety, high sealing performance, and convenient operation. The cable crossing device includes a cable crossing device body and plug. [0003] However, the temperature and pressure r...

Problems solved by technology

[0003] However, the plugs of the existing structure are not ideal in terms of temperature and pressure resistance, especially when a blowout occurs, the plug will often fail to seal in the face of instantaneous high pressure, and there is no better solution for high-temperature oil wells.
